Split Rocks

Split Rock is an operating iron ore asset situated within the Marble Bar district, East Pilbara, Western Australia — one of the most geologically aggressive environments on the continent. The terrain is characterised by exposed BIF (Banded Iron Formation) ridgelines, extreme thermal cycling exceeding 50°C, and pervasive red fine-dust (red dirt) conditions. B2B suppliers must engineer for accelerated filter degradation, abrasion-grade wear liners, and sealed bearing assemblies across all mobile and fixed plant equipment.

The site operates under rotating FIFO rosters, with crew mobilisation routed through Port Hedland as the primary fly-in hub. Operational continuity depends on reliable camp support infrastructure — including catering, laundry, medical, and telecommunications services. Given the remote classification of Marble Bar, vendor lead times are critical; B2B procurement strategies must account for extended supply corridors, minimum stockholding agreements, and contingency logistics protocols to prevent unplanned downtime.

Iron ore handling at Split Rock involves conveyor-intensive material movement across crushing, screening, and stockpile circuits. The abrasive nature of Pilbara hematite/goethite ore demands premium-grade conveyor belting, impact cradles, and ceramic-lined chute work. Dust suppression systems — both wet and dry — are operationally non-negotiable. B2B engineering suppliers should prioritise:

• High-abrasion conveyor belting (AS 1332 compliant)
• Sealed roller assemblies for red-dirt environments
• Modular screen media with rapid-change capability
• Dry fog or chemical dust suppression at transfer points

Operating in East Pilbara mandates strict Aboriginal Heritage compliance under the WA Aboriginal Heritage Act 1972 (as amended) and alignment with Section 18 consent protocols. B2B partners are increasingly evaluated on their capacity to support Indigenous procurement commitments, including subcontracting to Nyamal or Kariyarra-owned enterprises. ESG-aligned vendors offering RAP (Reconciliation Action Plan) credentials, local employment pathways, and low-emission equipment options hold a measurable competitive advantage in tender evaluations for this asset class.
